flip a coin 10 times and record the observed number of heads and tails. for example, with 10 flips one might get 6 heads and 4 tails. now, flip the coin another 20 times (so 30 times in total) and again, record the observed number of heads and tails. finally, flip the coin another 70 times (so 100 times in total) and record your results again. we would expect that the distribution of heads and tails to be 50/50. how far away from 50/50 are you for each of your three samples? reflect upon why might this happen?

Using basic demographic information (age, household income, marital status, etc.), you collect a random sample size 188 customers who accepted a special balance transfer offer from a major credit card company six months ago. The company wants to determine if there is evidence that it would profit by offering the deal to the population of customers with those same demographic characteristics. The sample mean balance transfer amount is 1,767 with a sample standard deviation of 442.Based on the information above, if the company were to perform a hypothesis test at α = 0.05, what is the largest value it could specify in the null hypothesis and still fail to reject the null hypothesis?Hint: Think about the relationship between hypothesis tests and intervals. Specifically, think about how a test done at would relate to a 95% confidence interval? please add step by step instructions.Thank you,

Religion and Theology Assignment Writing ServiceYou and a friend are talking about the probability of getting a heads on a single toss of a fair coin. Your friend insists that you are more likely to get a heads on a single toss of a fair coin than a tails. Is your friend correct, why or why not? If we were to toss the fair coin an infinite number of times, what would we expect?

Joan’s Nursery specializes in custom-designed landscaping for residential areas. Labor costs of planting trees are important to the nursery, so they compiled the planting times for the first and last trees planted on 30 consecutive work days. Based on this sample, is there a difference in the time it takes between the first and last tree? Treat the data as paired. a. State the null and alternative hypotheses. b. What is the test statistic? c. What is the p-value? d. State your conclusion.

The mean cost of domestic airfares in the United States rose to an all-time high of $390 per ticket. Airfares were based on the total ticket value, which consisted of the price charged by the airlines plus any additional taxes and fees. Assume domestic airfares are normally distributed with a standard deviation of $105. Use Table 1 in Appendix B.a. What is the probability that a domestic airfare is $545 or more (to 4 decimals)?0.0793b. What is the probability that a domestic airfare is $265 or less (to 4 decimals)?c. What if the probability that a domestic airfare is between $310 and $470 (to 4 decimals)?d. What is the cost for the 5% highest domestic airfares? (rounded to nearest dollar)$ or – Select your answer –

Analyses performed in studies with more than 2 groups often indicate the groups are significantly different but do not identify which groups are different. In this case, a second analysis is performed to identify where the significant differences between groups are. These secondary analyses are referred to as:Exploratory analysesPost hoc analysesConfirmatory analysesReliability analyses

In the 2012 National Football League (NFL) season, the first three weeks’ games were played with replacement referees because of a labor dispute between the NFL and its regular referees. Many fans and players were concerned with the quality of the replacement referees’ performance. We could examine whether data might reveal any differences between the three weeks’ games played with replacement referees and the next three weeks’ games that were played with regular referees. The pair of dotplots shown display data on the total number of penalties called in the game, again separated by the type of referee. Select all the statements below which might reveal whether the two types of referees differ with regard to the distributions of this variable.

For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding.In a marketing survey, a random sample of 984 supermarket shoppers revealed that 280 always stock up on an item when they find that item at a real bargain price.(a) Let p represent the proportion of all supermarket shoppers who always stock up on an item when they find a real bargain. Find a point estimate for p. (Enter a number. Round your answer to four decimal places.) (b) Find a 95% confidence interval for p. (For each answer, enter a number. Round your answers to three decimal places.)lower limit upper limit Give a brief explanation of the meaning of the interval. We are 95% confident that the true proportion of shoppers who stock up on bargains falls within this interval.We are 5% confident that the true proportion of shoppers who stock up on bargains falls within this interval. We are 95% confident that the true proportion of shoppers who stock up on bargains falls outside this interval.We are 5% confident that the true proportion of shoppers who stock up on bargains falls above this interval.(c) As a news writer, how would you report the survey results on the percentage of supermarket shoppers who stock up on items when they find the item is a real bargain? Report the margin of error.Report p̂ along with the margin of error. Report p̂.Report the confidence interval.What is the margin of error based on a 95% confidence interval? (Enter a number. Round your answer to three decimal places.)

When 3 or more groups are included in an ANOVA, and the probability level indicates that the null hypothesis should be rejected, what does this tell the researcher?-Specific post hoc analyses should be done to determine where there are group differences-That each mean is significantly different than every other one-It will be necessary to perform t-tests on each of the pairs of means to determine which pair (or pairs) is (are) different -which groups are different from which other groups
